I'm sorry, but your question is too vague to properly answer. There might be a problem with the translation as well.
There are many sites on the internet that document how to configure an FTP site.

If you wish to connect from the internet to your home PC, then you need to configure port forwarding on your router.

You need to understand the difference between active and passive mode and why you need to use passive mode when using port forwarding.

You should also verify that the Windows firewall allows access.

Personally, if you need to access your pc from an internet based machine, I would recommend using OpenSSH and SFTP instead of FTP. SFTP will encrypt your data while it flows over the internet. That also eliminates the problem with FTP's control and data channels.

If you require further assistance, then you will need to provide specific details about your FTP site, how you authenticate users and what NTFS permissions have been assigned to the folders. You would need to clearly explain how you are testing, what commands you execute, and what machines are used in the test.
Please remember that this is an English based web site and that the vast majority of us cannot read Chinese. If you would post a screen image, which normally would be quite helpful, we can't read what it says anyway. You may have better luck asking your question on a Chinese based site.
